The first bite is a small shock. Sweet, salty, deeply savory — warm miso-caramel pools against impossibly creamy filling that just barely holds its shape. These Japanese-inspired cheesecake bites get their magic from white miso paste folded into the cream cheese batter, adding a subtle umami richness that makes you reach for a second bite before you have finished the first. The toasted sesame and almond crumble crust shatters underneath, and the whole thing comes together in your air fryer in under 20 minutes of cook time.

At just 4 grams of net carbs per serving, these bites sit squarely in keto-friendly territory. Cream cheese and butter supply 47 grams of fat per serving, making up roughly 86 percent of the total calories. The eggs and cream cheese together deliver 11 grams of protein, so you finish your meal on a genuinely satisfying note without any risk of kicking yourself out of ketosis.

Each cheesecake bakes in its own ramekin, which means no delicate slicing, no crumbling edges, no communal pan to worry about portioning. The air fryer's concentrated heat produces a beautifully set top in a fraction of the time a full oven needs. You can have these on the table in just over 30 minutes, from mixing bowl to first bite — and they taste even better cold from the fridge the next day.

Ingredients (serves 4)

For the sesame almond crust and crumble:

  • 2/3 cup (67g) almond flour
  • 2 tablespoons (28g) unsalted butter, melted
  • 2 tablespoons (18g) white sesame seeds
  • 1 tablespoon granular erythritol or monk fruit sweetener
  • Pinch of fine sea salt

For the miso cheesecake filling:

  • 8 ounces (226g) full-fat cream cheese, softened to room temperature
  • 1 large egg
  • 1 large egg yolk
  • 3 tablespoons granular erythritol or monk fruit sweetener
  • 2 teaspoons white (shiro) miso paste
  • 2 tablespoons (30ml) full-fat coconut cream
  • 1/2 teaspoon pure vanilla extract

For the miso-caramel drizzle:

  • 2 tablespoons (28g) unsalted butter
  • 2 tablespoons granular erythritol or monk fruit sweetener
  • 1 teaspoon white (shiro) miso paste
  • 2 tablespoons (30ml) full-fat coconut cream
  • Pinch of flaky sea salt (such as Maldon)

Instructions

  1. Preheat the air fryer to 320°F (160°C). Lightly grease four 4-ounce (120ml) oven-safe ramekins with butter or cooking spray.

  2. Make the crust mixture. In a medium bowl, stir together the almond flour, melted butter, sesame seeds, erythritol, and salt until evenly combined and crumbly. Set aside 3 tablespoons of the mixture in a small bowl — this becomes your crumble topping. Divide the remaining mixture among the four ramekins, pressing it firmly and evenly into the bottom with the back of a spoon.

  3. Air fry the crusts. Place the ramekins in the air fryer basket, leaving space around each for airflow. You may need to work in two batches depending on your air fryer size. Bake at 320°F (160°C) for 4 minutes until the edges turn lightly golden. Spread the reserved crumble mixture on a small piece of parchment paper and slide it into the basket alongside the ramekins for the last 2 minutes. Remove the crumble and set it aside to cool and crisp up.

  4. Prepare the filling. While the crusts bake, beat the softened cream cheese in a large bowl with a hand mixer or whisk until completely smooth, about 1 minute. Add the erythritol and miso paste and beat until incorporated. Add the egg, egg yolk, coconut cream, and vanilla, mixing on low speed just until the batter is smooth and uniform. Do not overbeat — you want a dense, creamy batter, not an airy one. A few small lumps of miso are fine; they will melt during baking.

  5. Fill the ramekins. Lower the air fryer temperature to 300°F (150°C). Pour the filling over the par-baked crusts, dividing it evenly among the four ramekins. They will be nearly full — leave about 1/4 inch of space at the top.

  6. Bake the cheesecakes. Air fry at 300°F (150°C) for 12 to 14 minutes. The cheesecakes are done when the edges are firmly set but the centers still jiggle noticeably when you gently shake the ramekin. They will look slightly underdone — that is exactly right. They firm up considerably as they cool.

  7. Make the miso-caramel drizzle while the cheesecakes bake. Melt the butter in a small saucepan over medium-low heat. Add the erythritol and stir constantly until it dissolves into the butter, about 1 minute. Whisk in the miso paste until smooth, then pour in the coconut cream. Simmer gently for 1 to 2 minutes, stirring the whole time, until the sauce thickens just enough to coat the back of a spoon. Remove from heat and stir in the flaky salt. Keep warm.

  8. Cool the cheesecakes. Remove the ramekins from the air fryer and let them sit undisturbed for at least 10 minutes. The residual heat will finish setting the centers while keeping the texture silky and custardy.

  9. Assemble and serve. Spoon the warm miso-caramel drizzle over each cheesecake, letting it pool slightly in the center. Break the toasted sesame crumble into rough pieces and scatter generously on top. Serve warm for a softer, custard-like texture, or refrigerate uncovered for at least 1 hour (then cover) for a denser, fudgier Japanese-style cheesecake.

Tips & Variations

Choose the right sweetener for the drizzle. Allulose is the best option for the miso-caramel because it actually caramelizes like real sugar, giving you a proper golden sauce with deep butterscotch notes. Erythritol works but will not caramelize — you will get a buttery miso sauce that is still delicious, just without the amber color. A granular monk fruit blend splits the difference nicely.

Soften your cream cheese completely. Cold cream cheese creates lumps that no amount of mixing will smooth out. Leave the block at room temperature for at least 30 minutes before starting, or microwave it in 10-second bursts until it is pliable but not warm. Press a finger into the center — it should yield easily with no resistance.

Do not skip the extra egg yolk. The additional yolk (on top of the whole egg) is what gives these bites their dense, custardy richness. Using two whole eggs instead would introduce too much egg white protein, pushing the texture toward a lighter, puffier cheesecake rather than the fudgy one you want. Save the leftover egg white for a keto-friendly egg white omelette the next morning.

Watch for hidden carbs in miso paste. White (shiro) miso is the lowest-carb miso variety, running roughly 3 to 4 grams of carbs per tablespoon depending on the brand. Red (aka) miso and barley-based miso are higher in carbs and will push the net carb count up. Always check the nutrition label, and stick with a traditional rice-based white miso for the best flavor balance here.

These improve overnight. As with most cheesecakes, the flavor deepens and the texture becomes smoother after a night in the refrigerator. Make them in the evening, drizzle and top just before serving the next day, and you will be rewarded with an even more cohesive miso-caramel flavor running through every layer.

Frequently Asked Questions

Can I use a different keto sweetener in this recipe?
Absolutely. Erythritol, monk fruit blends like Lakanto, and allulose all work well throughout this recipe. Erythritol can sometimes produce a faint cooling sensation in the filling — if that bothers you, a monk fruit and erythritol blend minimizes it. For the caramel drizzle specifically, allulose gives the most authentic result because it browns and thickens like real sugar. Liquid stevia drops work for the filling but you will need to reduce the amount significantly and the crust will lack structure without the bulk of a granular sweetener, so keep the granular sweetener for the crust regardless.
What if I cannot find white miso paste?
White miso is the key to this recipe's personality, but if you cannot locate it, you can approximate the savory-sweet depth with 1 teaspoon of tahini mixed with 1/4 teaspoon of soy sauce or coconut aminos per teaspoon of miso called for. The flavor will not be identical, but you will still get that intriguing salty-sweet contrast that makes this cheesecake special. Look for white miso in the refrigerated section near the tofu at most grocery stores, or check the international aisle. Asian grocery stores always stock it, and it keeps for months in the fridge once opened.
How do I store and reheat these cheesecake bites?
Let the cheesecakes cool completely in their ramekins, then cover tightly with plastic wrap or transfer to an airtight container. They keep in the refrigerator for up to 5 days and genuinely taste better on days two and three as the miso flavor mellows and melds into the cream cheese. For longer storage, wrap each ramekin in plastic wrap and then foil; they freeze well for up to 2 months. Thaw overnight in the refrigerator. To serve warm, air fry at 250°F (120°C) for 3 to 4 minutes — or simply enjoy them cold, which gives the densest, most fudge-like texture.
Can I make this dairy-free for vegan keto?
You can adapt this recipe for vegan keto, though the texture will differ. Replace the cream cheese with a coconut cream-based vegan cream cheese — check the label carefully, as some brands add tapioca starch or other thickeners that raise the carb count. For the eggs, mix 2 tablespoons of ground flaxseed with 5 tablespoons of warm water and let it sit for 5 minutes until thick and gel-like. Swap the butter for refined coconut oil throughout. The cheesecake will be slightly softer and more mousse-like, but the miso-caramel flavor carries through beautifully.
Why did my cheesecakes crack on top?
Cracks happen when cheesecakes are overbaked or cool too quickly — and the air fryer's intense, direct heat makes this more likely than in a conventional oven. The single most important step is pulling them out while the centers still jiggle visibly. They will look underdone, but they set fully as they cool. Keep the temperature at 300°F or lower; going higher speeds up browning but almost guarantees cracking. Letting them cool gradually inside the ramekins on the counter, rather than in a drafty spot, also helps. If you do get a crack or two, it will not affect the taste at all — the miso-caramel drizzle and sesame crumble will cover it completely.
